Question

Which vector best describes the translation below?

Answer 1

Answer: Choice A) <9,0>

Step-by-step explanation:

Focus on one of the points in the figure on the left. Let's say we go for the upper left corner point (-7, 4)

Notice it moves to the corresponding image point (2,4). It has shifted 9 units to the right to follow the translation rule
`(x,y) \to (x+9, y)`. We've added 9 to the x coordinate, and the y coordinate stays the same.

This notation can be shortened to <9, 0>

In general, the notation
`(x,y) \to (x+a, y+b)` is shortened to the translation vector notation
`< a, b >`. In this case, a = 9 and b = 0.
